The Lowdown

G’day, Rusty here, and I’ve been staring at the charts for Jaconé, and let me tell you, it’s a slow burn before the fire. The first week is a bit of a tease, with small, clean fun but nothing to really get the heart racing. The real action, the stuff that’ll have you calling in sick, starts to build from the 26th, and the last few days of July into the first of August are where the magic is. The water temp is sitting right around 72°, which is dead average for this time of year, so just boardies and a light spring suit.

We’ve got a few days of mellow, clean surf to kick things off. Friday the 17th and Saturday the 18th are all about waist-to-chest high waves from the SE, with light offshore or cross-off winds. The energy is moderate (329 and 287), and it’s a consistent spot, so you’ll find a wave. This is perfect for a longboard or a fish, but it’s not going to set the world on fire. Sunday morning the 19th sees a little bump in size to 5ft from the E, with a clean offshore wind, and the energy climbs to 418. Still fun, but we’re waiting.

Then there’s a bit of a lull. Monday the 21st drops off, and then Tuesday to Thursday the 23rd and 23rd are small and ordinary. The energy drops below 200, and the wind stays light but the swell is just not there. Thursday afternoon the 23rd does have a 3ft SSW swell with a longer period of 11 seconds, but it’s a cross-shore wind and only a marginal call. It’s a bit of a blank stretch until the 24th.

The most promising run starts on Sunday the 26th. The morning session is looking very good. A solid 5ft swell from the S, with a period of 11 seconds, combines with a near glassy offshore wind. The energy is strong at 539. This is a proper groundswell, and at a consistent spot, you’ll get clean, well-shaped sets. The afternoon gets a bit messy with a cross-onshore wind, so make it a dawn patrol.

Monday the 27th has a bigger, longer-period S swell (12 seconds, 340 energy), but the wind is onshore and messy. Keep an eye on it, but it’s not the pick.

Now, the standouts. If you’ve got the skills, you’re looking at the 30th of July, and the 1st of August. Thursday the 30th afternoon has a 6ft SE swell with a 13-second period, blown by a fresh offshore wind. The energy is very strong (1309). This is a powerful, clean wave for experienced surfers. Friday the 31st is even better, with 6ft to 5ft SE swell, that same 13-second period, and fresh to light offshore winds. The energy is still well over 1000, and the call is "excellent." This is a top-tier session.

But the absolute standout, the one you circle on the calendar, is Saturday the 1st of August. The morning is a 8ft SE swell, but the afternoon is the bomb. A 8ft SE swell with a 15-second period, blowing a light offshore breeze, and the energy is off the charts at 3148. This is a very long period groundswell, so it will be breaking deep and fast, with long lulls between sets. The excellent rating is for experienced surfers only – this is too big for beginners. It’s a consistent break, and with that size and direction, the sets will be proper. Crowds are sometimes a factor here, so expect company for the best waves of the forecast.

So, to sum it up: the first week is small and clean for the longboard crew. The second week is where the power comes in. The best wave on offer is the afternoon of the 1st of August, with the 30th and 31st of July as close seconds. Get out there.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
